Ask your steward or a local officer for a Form 1187 and fill it out. Part of it must be completed by you, and part by the local. Your union dues will automatically be deducted from your pay check. You can get more information from your steward or another union officer. If you work in a very small office where you have difficulty getting information, contact Organization Department Director Anna Smith, 1300 L St. NW, Washington, DC 20005. The phone number is 202-842-4227. - See more at: http://www.apwu.org/questions-and-answers#19
